# Blind Source Separation Based on a Single Observation

### Damjan Zazula, Aleš Holobar

#### Abstract

This paper deals with a novel approach to the compound signal decomposition. It takes advantage of blind source separation using the algorithm for convolution kernel compensation (CKC). We derive a version which cope with compound signals, mixtures of several source contributions, even if only a single observation is available. Our novel approach detects and separates the triggering instants of all source symbols which contribute to the processed observation. The obtained decomposition is very robust and accurate. We experimented with synthetic signals having characteristics similar to the electrocardiographic (ECG) signals. Also at signal-to-noise ratios (SNRs) as low as 0 dB, the obtained average true positive statistics for the detected source- symbol triggerings was 98±1%, average false positive statistics 2±1%, and false negative statistics 3±2%.
